JP5548921B2 - Heat source air conditioner - Google Patents

Description

The present invention uses a low-temperature heat source such as solar heat, exhaust heat from a fuel cell, exhaust heat from a gas engine power generator, etc. to dehumidify indoor air, and raises the temperature and humidity of the air by ventilation to cool the exhaust. In addition, a key technology for realizing an air conditioner using a heat source capable of performing cooling with high energy efficiency by skillfully combining them is proposed. As cooling devices in this field, absorption refrigerators, adsorption cooling devices, desiccant dehumidifying devices and the like have already been realized and used, but all have low energy efficiency. There are no examples of good cooling systems with skillful combination with ventilation.

  A conventional cooling or refrigeration system using a heat source such as an absorption type uses a relatively low temperature heat source of about 85 ° C., and uses a low temperature heat source of about 60 ° C. such as solar heat for high performance and economy. Because it was not possible to realize an effective and effective device, there is exhaust heat that should be discarded such as high-temperature factory exhaust heat and special heat equipment exhaust heat, or where gas fuel is allowed to be consumed Many were used and the market was limited. For this reason, the production volume of the equipment is limited, and there are several companies with a scale of 1000 units / year, and operators of electric air-conditioners of the electric compression refrigeration cycle method, for example, 10 million units / Compared with a large number of companies that produce a large amount of the year, there was a big gap in the cost of the product.

Moreover, with the exception of refrigeration devices that use heat sources and refrigeration devices with complex special structures, such as double-effect and triple-effect absorption refrigeration machines, adsorption dehumidifiers and chillers that are generally used for cooling are used. The COP indicating the energy efficiency (ratio of the cooling capacity to the heat source heat consumption) is as low as about 0.5, that is, only the heat quantity of the cooling capacity of about 0.5 for the heat source heat quantity of 1 can be obtained. There is a drawback that a large amount of heat source heat is required to obtain cooling capacity. Further, the volume of the apparatus is more than twice as large as that of an air conditioner using an electric compressor, and thus the product cost has to be extremely high.
A combination of a desiccant dehumidification mechanism using a low-temperature heat source and a cooling mechanism that skillfully utilizes exhaust heat of ventilation that can operate with minimal energy consumption as an effective means to overcome this. Focusing on the fact that it is an effective method, the technology for realizing and realizing this method is the technical field of the present invention.

In both Patent Documents 1 and 2, although the temperature and humidity, that is, the enthalpy, of exhaust air exhausted by ventilation is increased to cool the indoor space as a result, both use a heating source or a cooling source. In other words, this is an example of performing ventilation cooling or ventilation dehumidification using external energy, and it cannot be said that the energy efficiency is excellent. Certainly, these technologies have the effect of reducing the loss of air-conditioning energy due to ventilation compared to a system in which room air is simply exhausted from the interior space of a building. Moreover, both have the effect of reducing the energy loss due to ventilation by installing a temperature and humidity between the indoor and outdoor air called a ventilation element or total heat exchanger, that is, a total heat exchanger, and desiccant dehumidification In terms of having a function and a dehumidifying operation function, it is an excellent system in terms of ensuring air-conditioning comfort through humidity control.

However, in addition to consuming the energy source for heating or cooling as described above, there is no synergistic effect between the desiccant dehumidifying function and the ventilation air-conditioning using exhaust, and the energy consumption reduction effect is limited. That is, in Patent Document 1, a great amount of energy is consumed for realizing the cooler and the reheater, and in Patent Document 2, a great amount of energy is also consumed for the coolers 6 and 7 and the heating re-means 4. In other words, for the function of dehumidification, it is impossible to see a technology that suppresses energy consumption in the corner and cooling function.

Japanese Laid-Open Patent Publication No. 06-123444 JP 2000-1111096 PR

The problems to be solved by the present invention are the realization of a device that can cool an indoor space with little consumption of a power source or a heat source, and a low-temperature heat source that can be obtained in a very wide range, that is, 60 ° C. that can be obtained by solar heat. Realization of a dehumidifying device that can operate using relatively low temperature thermal energy and natural energy, such as heat before and after, exhaust heat around 65 ° C. of a low temperature operation type fuel cell of about 70 ° C., and further It is the realization of a cooling system that can enhance the effect by combining both. The aim is a high-efficiency COP of 1.2 or more, which is the total energy efficiency, cooling comfort that is affected by the temperature and humidity of the indoor space and air flow, etc., due to cooling operation, and compact, consumer equipment The realization of an economical system that can withstand practical use.

As a specific problem, the energy efficiency COP of the desiccant cooling device currently realized as a device using the above heat source is about 0.5, and only 50% of the heat consumption can be obtained. In order to obtain the amount of heat, a large amount of energy is required, and there is a problem that the volume of the apparatus becomes so large that practicality is lost. In order to solve this problem, it is important that the COP is a device having high energy efficiency performance, and the inventors set the target value to 1.2. For example, when considering a 5000 Kcal / h (5.8 KW) air conditioner for residential use, a COP 0.5 level desiccant adsorption type air conditioner currently used for consumer use and a COP of 1.2 or more, which is the target of the present invention There are significant differences in the capacity of solar water heaters that are required when operating high-performance cooling systems.

In other words, in the case of 400 W / sq.m, where the solar heat collection characteristic of the panel is an average characteristic, the total area of the required panel is 2.4 times as large as 12 square meters versus 29 square meters, and remains at COP 0.5. However, there are problems such as an increase in costs caused by the large panel area, restrictions on installation locations such as roofs, and an increase in construction costs. At the same time, the device becomes larger and the product cost becomes higher, so that it has not become popular.
A further important issue is the volume and cost of the device. Considering the overall cost of the desiccant cooling device, it is important to reduce the material cost of the adsorbent element coated with the adsorbent used for the desiccant as well as reducing the material cost by downsizing the device. Accordingly, it is an important issue how to reduce the size of the adsorbent element to reduce the material cost, reduce the size of the cooling device to reduce the cost, and ensure the cooling capacity in that state.

The target value is as small as an air conditioner that uses a compressor and an electric motor with a refrigeration cycle as a drive source, but specifically, it was separated into the current indoor unit and outdoor unit. We want to aim for a volume twice that of the outdoor unit of the so-called split type air conditioner.
In order to solve the above problems, it is necessary to improve the volume-based performance of the adsorbent element and reduce the cost, and it can be said that the contrivance of the structure mechanism is one of the problems.
As described above, the present invention invents and proposes a new cooling system that makes use of the dehumidifying function of the adsorbent and does not require energy such as power and heat. Furthermore, the present invention proposes a technique for constructing a new cooling system by combining both the dehumidifying system of the adsorbent and the new cooling system, and intends to solve the above-described problems. Therefore, it can be said that the most important problem is to materialize the cooling method, the detailed structure, and the material.

In claim 1, indoor air is introduced and divided into two, one air is used as ventilation air, and the other indoor blow-out air is discharged by increasing the amount of heat (enthalpy) of the air to be ventilated and exhausting it outside the room. A method of cooling and cooling the room is presented. A specific example is shown in the cooling unit indoor unit 102 in FIG.
Since this method cannot dehumidify the room air, a desiccant type dehumidifier is presented as a method for dehumidifying the inlet room air of the cooling device of claim 1. It will be described later that docking of these two functional devices produces a very high effect.

The principle of the water evaporative cooling method will be described in detail. That is, a method of spraying water and humidifying and cooling with the latent heat of evaporation of water is well known. The garden watering and sprinkling cooling systems use this principle. When this change in the air state is shown, indoor air is shown at point A on the wet air diagram (shown in FIG. 1). Due to the latent heat of water evaporation, the air moves on the isenthalpy line from the point A to the point B, which is the intersection of the 100% humidity line, and the temperature decreases but the humidity increases. If this is used for indoor cooling, the humidity in the room rises and residents often feel uncomfortable.

  As a method that further improves this method, there is a method in which indoor air is divided into two parts, water is sprinkled into one air to cool the air itself, and the other air is cooled with this sprinkled and cooled air. If heat exchange is performed ideally, the other air can be cooled to point F, which is in the middle of the dew point temperature E, without increasing the absolute humidity. At this time, the temperature and humidity of one air rise from point B to point G. That is, the ratio of the air volume of one air to the air volume of the other air is inversely proportional to the ratio of (IA-IF) and (IG-IB), which is the enthalpy change. Here, I represents enthalpy, and IE represents the enthalpy of air at point E.

Next, consider not dividing the room air into two at the point A, but dividing it into two at the point C after being cooled with one air according to the above principle. One of the divided air cools the whole air before the division from point A to point C, and the other air is heated not from point B but from point C to point J to be humidified. As a result, (IG-IC) has a larger enthalpy difference than (IA-IF), and therefore 75% of the air can be cooled with an air volume of even less than 30%, for example, about 25%. As a result, the ratio of one air volume of exhaust heat decreases and the ventilation volume decreases. This can produce a great effect that the same indoor air cooling amount can be secured with a small amount of ventilation. This is the basic technique shown in claim 1 and is shown in the cooling device indoor unit 102 of FIG.

The indoor cooling heat exchangers 1, 2, and 3 and the indoor water evaporators 4, 5, and 6 shown in FIG. 2 are composed of finned tube heat exchangers in which tubes are arranged vertically, and are divided by a partition surface at the center. The entire amount of room air passes through the flow path and is cooled by the heat exchanger for room cooling at that time. On the other hand, this air is divided into a small amount and a large amount at the outlet, and a large amount of air is blown into the room. At this time, since tap water is sprinkled from the upstream side of the three heat exchangers, a small amount of air is cooled by the latent heat of the water and at the same time the fin tube heat exchanger is cooled. Since this heat exchanger operates in a state where water is sprayed, it is called an indoor water evaporator here.

  The water evaporator and the indoor cooling heat exchanger are connected one above the other by a number of vertical tubes, so that the water injected inside circulates inside the tubes and repeats evaporation and condensation to generate heat. Tell. That is, heat is transferred from the indoor cooling heat exchanger to the indoor water evaporator. As a result, the total amount of room air flowing therethrough is cooled by the small amount of room air after division. A small amount of room air evaporates water and takes heat from the entire amount of room air, resulting in high temperature and high humidity. In FIG. 1, the enthalpy rises to the point H and is exhausted outside the room. Ventilation will occur by this amount. As a result, the indoor air is cooled by the ventilation air.

Further, a technique for enhancing this effect is presented in claim 2. In order to further improve the heat exchange, this is a method of exchanging heat in the counterflow state between the entire amount of air and a small amount of air after the division. That is, when heat is exchanged ideally using a very high performance heat exchanger, the total amount of air is cooled to point C and ideally to point E, while the small amount of air after one division is H The point beyond the point is ideally humidified and heated to point J. In this case, (IJ-IC) has a much larger enthalpy difference than (IG-IB), as is apparent from the wet air diagram. For this reason, it can be seen that a small amount of divided air can be achieved with a smaller amount.

In order to realize this concretely, as shown in FIG. 2, three indoor cooling heat exchangers and three finned tube heat exchangers constituting three indoor water evaporators are separated from each other thermally and structurally. This is an example of installing. When a large number of these heat exchangers are installed to exchange heat ideally, the indoor blown air becomes point E in FIG. 1 and the outdoor blown air becomes point J. The important thing here is that the heat exchanger for indoor cooling and the indoor water evaporator are related to heat exchange as if the most upstream and the most downstream air were connected by a heat pipe like this case. It is to be configured. Thereby, the arrival point of each air can approach the E point and the J point as much as possible, and the characteristic which cools the room | chamber interior of the whole apparatus can be improved. Of course, the indoor cooling heat exchanger and the indoor water evaporator, which are located at the most upstream and the most downstream in the air flow, are arranged in the order in which the respective airs face each other, and constitute a heat transfer relationship with each other.

The invention according to claims 1 and 2 is an air-conditioner that uses this principle. In this air conditioner, as can be seen from the above description, all the working air operates at atmospheric pressure. In addition, a mechanism that consumes a large amount of energy such as a compressor or a heating device is not used to cool one air. As shown in FIG. 2, the only energy consumed is only the motor power consumed by a fan motor or a water pump that drives a blower necessary for circulating air. This is energy consumption that is about one-tenth of the power consumed by the electric compression air conditioner and the heat source heat consumed by the absorption refrigerator.

  The inventions of claims 1 and 2. It cools the room and exhausts the sultry air with high enthalpy to the outside of the room to exert the cooling effect and at the same time have the ventilation effect. In addition to theaters and department stores where many people gather, it is currently recommended and regulated by the law to ensure ventilation, and ordinary electric-powered refrigerant circulation air conditioners require the addition of a ventilation duct device, which requires a large facility. It is an invention that presents a system that is extremely effective as a next-generation air conditioning system in view of the current situation that has major problems such as the increase in required air conditioning capacity due to the increase in cost, cost, and exhaust loss.

As described above, a specific measure for cooling one air with the other air is to flow both air through a flow path separating the partition walls to exchange heat through the partition walls. By the so-called heat pipe function that connects the heat exchanger with the other air and the heat exchanger with one air by a pipe line, fills the pipe line with an evaporation medium such as water, and transfers heat by natural circulation of the water. It is possible to exchange heat.

  The performance of heat exchange between both air has a great influence on the performance of the entire air conditioner. The invention of claim 2 is presented as means for enhancing this performance. That is, a plurality of indoor cooling heat exchangers and indoor water evaporators are provided to improve the heat exchange performance with air. Naturally, each indoor cooling heat exchanger and indoor water evaporator are placed in a heat exchange relationship, and the indoor water evaporator is in a relationship cooling the air cooling heat exchanger. The technique of claim 2 is a technique for adopting a so-called countercurrent heat exchange system that can obtain a high heat exchange performance.

That is, it is premised that a large number of indoor cooling heat exchangers and indoor water evaporators are installed with double or triple structures in the direction of ventilation. In claim 2, two or more air-cooling heat exchangers and indoor water evaporators are installed, respectively, so that the air cooling heat exchanger and the indoor water evaporator on the most upstream side and the most downstream side respectively exchange heat. It is made to constitute a mutually opposing flow.

The above relates to an invention for cooling indoor air.
Actually, in addition to this, humidity control, specifically dehumidification is required. Claim 3 is a technique for incorporating a desiccant dehumidifier in combination with claims 1 and 2. Usually, in a cooling device using a desiccant, the desiccant material and air are brought into contact with each other to dehumidify and at the same time the temperature is increased. In FIG. 1, air moves from point A to point AA. Normally, this air is cooled with outdoor air or the like, and then water is sprinkled and humidified to adjust the air to an appropriate temperature and humidity, thereby completing the cooling.
In the present invention, the dehumidified and heated air (point AA) is directly introduced into the air conditioning apparatus described in claims 1 and 2 for cooling, and the temperature and humidity adjustment by outdoor air cooling and humidification is unnecessary. is there. However, it is effective to improve heat efficiency by recovering heat consumption by exchanging heat between the air before and after the desiccant dehumidifier 21 as shown in FIG.

According to this method, the indoor air inlet of the cooling unit indoor unit 102 is introduced as it is with high temperature and low humidity indoor air from the desiccant dehumidifier 21, and as a result, the inlet temperature of all indoor air is relatively high. As described above, the temperature and humidity of the room air that is divided and exhausted to the outside as a result becomes high-temperature and high-humidity air as indicated by the JJ point shown in FIG. The driving will be in line with the goal to do. Therefore, installing a cooling device using outdoor air downstream of the desiccant dehumidifier 21 or adjusting the temperature and humidity by spraying water is not an effective measure.

The desiccant dehumidification operation is stopped when the humidity of the room air is low, and is activated when the humidity is high. Even with such switching, the cooling effect of the room air can be maintained in the cooling device of the present invention. Therefore, claim 4 proposes to stop the operation of the desiccant dehumidifying operation due to humidity. Specifically, the desiccant switching damper shown in FIG. 2 is switched to control the room air so that it does not pass through the desiccant dehumidifier 21, and the supply of the heat source medium is stopped.

In the present invention, a technique for further enhancing the effect of the indoor air conditioner is presented in claim 9. The inventions of claims 1 to 4 are realized by exhausting a part of the indoor air to the outside. However, as a result of this, ventilation is always occurring during operation, and outdoor air of high temperature and high humidity is forcibly introduced into the room as much as the amount of ventilation. As a result, the cooling capacity loss due to this ventilation is large, and half of the effects of the above cooling device may be lost.

Claim 5 is easy to understand if it is considered as a system in which the interior and the exterior of claim 1 are reversed. The difference is that, in the case of claim 1, the amount of exhaust air to the outside is as small as about 30%, but in claim 5, the amount of air blown into the room considered as the ventilation air amount is larger than the amount of exhaust air to the outside. As a result, as shown in FIG. 2, if the ventilation amounts of both the cooling device indoor unit 102 and the cooling device outdoor unit 103 are set to be equal, the ventilation amount generated in portions other than the cooling device can be suppressed to zero. Become.
The cooling device shown in claim 5 uses only the technology equivalent to that of claim 1, but the ventilation loss caused by operating both of them together in one cooling device as in claim 9 and FIG. This is an epoch-making invention in realizing the effect of reduction.

Claim 9 specifically shows the technique. In this case, an air conditioner that is a cooling device indoor unit and an air conditioner that is a cooling device outdoor unit are combined and operated at the same time, thereby producing an effect of realizing a more advanced air conditioner.
What can be seen here is that if the exhaust air flow rate to the outside of the cooling device indoor unit 102 is set equal to the blowout air flow rate of the cooling device outdoor unit 103, the total air flow of the cooling device outdoor unit is about 20 times the total air flow of the cooling device indoor unit. Setting to a small ratio of ˜40% is a condition for realizing optimum operation when both are integrated.

A sixth aspect of the present invention replaces the indoor air treatment of claim 2 with an outdoor air treatment. Claim 7 is the same as the purpose and means for providing the function of adding humidity control function to claim 2 to claim 2.
As the heat source of the desiccant dehumidifier 101, many types of heat sources such as solar heat, fuel cell exhaust heat, gas engine cogeneration exhaust heat, heat pump condensation heat, and gas combustion heat can be used.

Claim 8 presents a technique that performs the same function as claim 4, but there are significant differences. That is, claim 8 does not detect the humidity of the outdoor air that is the working air, but rather controls the operation by detecting the humidity of the indoor air that is the air conditioning target. The humidity changes depending on the sensible heat load and the latent heat load in the room, and it is important to detect the humidity. In the cooling apparatus shown in FIG. 2, the overall operation is controlled by a temperature / humidity sensor 25 for room air.

Claim 9 combines the air conditioner that handles indoor air of claims 1, 2, 3, and 4 and the air conditioner that handles outdoor air of claims 5, 6, 7, and 8 into one air conditioner. Basically, the air flow is changed by making the ventilation air volume of both sides the same and making the ventilation air flow in and out zero, so let's create an air conditioner that does not require other ventilation It is an aim. The embodiment shown in FIG. 2 is an example of this.

The tenth aspect uses a pipe line extending over both the indoor and outdoor cooling heat exchanger and the indoor or outdoor water evaporator and the heat transfer therebetween, and water or the like is contained in the pipe line. A method using a so-called heat pipe system in which a refrigerant is charged and heat is transferred by circulating the refrigerant by evaporative condensation is presented. Heat pipes have high heat transfer performance, a simple structure, and a highly reliable heat transfer system.

The following effects can be expected from the above invention.
1. It is possible to provide an air conditioner that effectively uses the latent heat of water evaporation to cool indoor air without using a heat source or a power source other than a fan motor and a water pump.
2. By combining an air conditioner that handles indoor air and an air conditioner that handles outdoor air, it is possible to provide an air conditioner that balances the amount of air flowing in and out of the room as the amount of ventilation.
3. A desiccant dehumidifier using a heat source is incorporated into the above apparatus to provide an air conditioner that efficiently performs both dehumidification and cooling.

4. When the indoor air humidity is detected and the humidity is low, the operation of the desiccant dehumidifier can be stopped to reduce the amount of heat source used.
5. The above air conditioner can be expected to reduce manufacturing depreciation compared to conventional air conditioners using a compressor or a refrigeration cycle, and can realize an air conditioner that uses less primary energy.

Wet air diagram showing air condition change of the present invention Structural drawing of a typical air conditioner according to the present invention

A typical example of a package type high-efficiency air conditioner embodying the above invention is shown in FIG. This apparatus comprises a lowermost desiccant dehumidifying device 101, an intermediate cooling device indoor unit 102, and an uppermost cooling device outdoor unit. The center of the desiccant dehumidifier is a desiccant dehumidifier 21, which has a structure capable of absorbing moisture by baking gelatin crystals as an adsorbent on the outer surface of the fins of the fin tube heat exchanger. When tap water of 25 ° C. is sent from the heat source medium pipe line 22 into the copper pipe of the desiccant dehumidifier, the room air guided by the desiccant switching damper 52 is adsorbed by the adsorbent of the desiccant dehumidifier. When this operation is continued for about 5 minutes, the desiccant switching damper is switched to introduce outdoor air, and at the same time, propylene glycol, which is a 60 ° C. heating medium heated by a solar water heater, is sent to the heat source medium pipe line 22. As a result, moisture is released from the adsorbent of the desiccant dehumidifier 21 and this moisture release operation is continued for about 5 minutes. This is repeated to dehumidify the room air, and in that case, it is dehumidified to the outdoor air. During the moisture discharge operation, heat is recovered from the outlet air by the heat recovery unit 23 and is radiated by the heat recovery radiator 24 at the entrance, so that the solar heat consumption is reduced. Although the heat recovery device 23 and the heat recovery heat radiator 24 are not shown, they are configured in a heat transfer relationship via a heat pipe.

The dehumidifying operation is performed only when the temperature and humidity of the indoor air is detected by the temperature / humidity sensor and it is determined that the operation should be performed at a high humidity. Otherwise, the dehumidifying operation is not performed.
Regardless of whether or not the dehumidifying operation is activated, the indoor air having an air volume of 1000 cubic meters / hour is sent to the cooling device indoor unit 102 through the indoor fan 62. The indoor air passes through the indoor cooling heat exchangers 1, 2, and 3 and is cooled, and 75% of the indoor air is blown into the room. The other 25% of room air at 250 cubic meters / hour is U-turned, humidified and heated by the indoor water evaporators 4, 5, and 6 and discharged outside the room. During this time, the indoor water evaporator is cooled, and the heat pipe tube disposed at the center is cooled to condense water on the inner surface. The condensed water falls in the heat pipe due to gravity and reaches the cooling device indoor unit, where it evaporates to cool the cooling device indoor unit, and finally cools the indoor air.

    The arrangement of the three indoor cooling heat exchangers of the cooling unit indoor unit and the arrangement of the three indoor water evaporators include heat pipes in the most upstream and the most downstream of the air flow. It is comprised by the integral fin tube heat exchanger. That is, the entire amount of room air and the 25% cooling air after the division are configured to exchange heat in a counterflow. The indoor cooling heat exchanger and the indoor water evaporator may be composed of four or more units, but the number is set to three in consideration of the complexity of the apparatus and the cost increase.

The cooling unit outdoor unit at the top has an air volume of 250 cubic m / hour which is 75% after outdoor air of 330 cubic m / hour is introduced and cooled by the outdoor cooling heat exchangers 11, 12 and 13. Is blown out. The remaining 25% is U-turned and cooled by the evaporation heat of the water sprayed through the outdoor water evaporators 14, 15, and 16, and becomes itself high humidity and high temperature and discharged outside the room. All the indoor and outdoor water evaporators described above are sprinkled by the six water sprayers 7 and humidify and heat the air passing therethrough while wetting the fin outer surface of the water evaporator.

Since the outdoor exhaust air volume of the cooling device indoor unit 102 and the indoor blowing air volume of the cooling device outdoor unit are the same 250 cubic m / hour, the incoming and outgoing air volumes are the same as the ventilation amount. This is set to the same air volume as the necessary ventilation of the building. As a result, in the normal operation of the air conditioner, it is necessary to ensure the amount of ventilation by the ventilation duct, but in this air conditioner, this is not necessary. As a result, there is no ventilation energy loss caused by exhausting cold air with additional ventilation.

In the above example, the temperature of the air blown into the room is cooled by about 10 Degg with respect to the suction room temperature. In addition, when the desiccant dehumidifying device 101 is not operating, the absolute humidity of the blown air is the same as that of the sucked air. However, by operating the desiccant dehumidifying device 101, the relative humidity of the indoor air is reduced by about 10%. Can do. This humidity is set by adjusting the operating time ratio of the desiccant dehumidifier.

The configuration and arrangement of the outdoor cooling heat exchanger and the outdoor water evaporator are based on the same idea as that of the cooling unit indoor unit 102.
As can be seen from the above examples, according to this air conditioner, almost no power or heat is used for indoor cooling, and low-temperature heat sources such as solar heat and exhaust heat from fuel cells can be used for dehumidification. Therefore, it is possible to provide an extremely excellent cooling function in terms of energy global environment. Incidentally, since the total energy efficiency COP = 1.2 or more can be obtained, the amount of primary energy used is small compared with the air conditioner using the electric compressor, and the air conditioner excellent in the global environment can be provided.
For heating, if the heating radiator 24 is heated through a solar heat medium, an air conditioner with the least amount of primary energy can be realized.
Furthermore, since the temperature and humidity can be set easily, it is possible to realize a cooling operation that is superior in comfort, health and the like as compared with a method in which the indoor heat exchanger is cooled by a conventional electric compressor.

  As can be seen from the above explanation, we can provide air conditioners with excellent global environment in a very wide market, so we have penetrated the approximately 4 trillion yen market, which is a vast world market for conventional electric compressor air conditioners. It is expected to go. Even 10% of this can constitute a 400 billion yen business, so we recognize that this is an extremely important invention from an industrial point of view.
